I restarted ntp today and noticed this in the logs:
Mar 17 07:12:41 bottom systemd[1]: /lib/systemd/system/system-update-cleanup.service:35: Unknown lvalue 'SuccessAction' in section 'Service'
Mar 17 07:12:42 bottom systemd[1]: /lib/systemd/system/system-update-cleanup.service:35: Unknown lvalue 'SuccessAction' in section 'Service'

Mar 17 07:12:50 bottom systemd[1]: Stopping Network Time Service...
So I looked at this line in the system-update-cleanup.service file:
It's the last line in the file in the [Service] section. A little research shows that this line seems to belong in the [Unit] section.
Dare I move it? Not sure if this is a known bug or if this is just some rot that's occurred over time on my debian systems.
I don't really know what this file does with respect to stopping ntp but it would be a bit odd if my system rebooted when I simply restarted ntp!
